We are just making final arrangements to despatch the latest edp Lift Roller Sizer. This particular unit is fitted with Stainless Steel plain rollers and is designed to separate 4 different sizes. It will be used on washed potatoes in this case, but can also be used on carrots, onions, sweet potatoes, broccoli and even brussel sprouts. We have a cone shaped roller model available as well.
